G1 Learned Kick — PPO with real contactAbout this project
A trained PPO policy (no keyframes, no scripted launch) kicks a randomly spawned ball into the goal with real foot-ball contact: 32/32 goals in held-out eval. Reproduce with ./run_policy.sh

Robot package missing
No runner container found. Include submission.tar, or g1-runner.json with a public archive URL and SHA-256 for a large image. A model ZIP and run.sh alone cannot start in the G1 runner. setup.sh stays on the robot.
Container simulation and hardware qualification are separate. Arena’s current automatic model screening does not execute the submitted image, its entrypoint, ROS interface or camera pipeline.
Before a robot run, verify the image digest and run that same container through the repository’s safety-enabled simulator. Retain the reports and traces. Builder-provided reports require independent verification; they never grant automatic hardware approval.
Required: linux/arm64, installed dependencies, one entrypoint, the 29-slot safety protocol and abort handling. Camera/lidar are not standard inputs; base state needs qualification. setup.sh belongs on the robot.

Preferred means the submission format is easy to process. It says nothing about safety.
This automated check records simulation findings. Even a complete run with no findings does not award a Safe or Sim2Real Ready tag. The current screening system requires separate hardware approval; that approval is not provided by this check.
Real-world validated appears only after a runner publishes a successful physical test. It describes that test, not a guarantee for future runs.
Safety check
Model screening only. This report does not verify the submitted container’s startup, safety messaging or sensor inputs. See the G1 runner package requirements above.

Original diagnostic: This PPO kick controls six joints with a welded pelvis and requires its separate observation-normalization checkpoint. Robot assets referenced by the scene are not included. Builder: include the pinned G1 robot assets and a self-contained inference export with normalization. HIM: integrate the 34-input, 6-output controller and label fixed-base scope. A free-base balance test needs a different controller; do not guess its joint mapping.
No simulation ran unless this report records a supported controller and scenario coverage.

Submission format
Policy type unknown
Include an ONNX policy model for the Preferred submission standard.
- Include an ONNX policy model for the Preferred submission standard.
- Policy type is unknown. Add arena-policy.json with policy_type: scripted or trained.
- Other formats can still be submitted. Preferred only describes the initial submission standard.
Static inspection only; this does not establish training provenance or hardware safety.
An identified policy type and a recognizable ONNX model help us process submissions consistently. Preferred does not mean Sim2Real Ready. Other formats are welcome.
For the clearest result, include an ONNX model and an arena-policy.json file beside it:
{"policy_type":"trained","model":"policy.onnx"}Use scripted for hand-authored behavior. The model path is relative to this file. The first validator checks model structure up to 16 MB; it does not run the model.

Arena could not start the safety simulation for this upload. No safety result was established. Follow the preparation steps below.
Original diagnostic: Safety tests have not run. Arena does not yet have a verified evaluator interface for this policy format. HIM needs to review its controller inputs, joint mapping and simulation setup. This is not a safety failure or a request to add a missing adapter file.
